24-Jul-2005 -- We started in Cologne on a nice Sunday morning and drove on the motorway via Nijmegen to the gateway IJsselstein (motorway A2). Here we turned into the direction of Schoonhoven and passed some traffic circles. At the traffic circle to Benschop our GPS indicated to be very near to N52E05. We parked our car between the street and the bicycle lane and located the confluence near beside easily. This was our first confluence below sea level, even though our GPS showed levels between -5 m and +1 m.
